The original Legend of Zelda blazed many trails for gaming, arguably setting the standard for what would eventually become the open-world genre. Seeing as how this is the 30th anniversary for the series as a whole, Nintendo has opted for a blast from the past and dug up some of the original design documents from this first game to give fans an insight into the initial process of its development.

A video which goes over the whole overworld map was recently shared by Nintendo of Europe, and some extra images of a few different rooms were also shown. It's an interesting tour of this part of the development to be sure; it's hard to believe that much of this game was drafted on graphing paper.

What do you think? Were you able to 100% complete the original Zelda without any exterior help? Were you able to beat it at all? Drop us a comment in the section below.
